초록
This is a study on the effect of the dentinal pretreatment method to the bond strength between dentin and glass ionomer cement. In this study, 196 human molar teeth with sound crown were used. The dentin surfaces of these teeth were exposed with wet trimmer and polished with # 800 Emory paper and teeth were divided into 7 groups according to the pretreatment agent and method. Each group has 4 subroups of the kinds of glass ionomers. The shear bond strength were measured by Instron Universal Testing machine model 1122. The data of the evaluations were then subjected to statistical analysis using one way ANOVA and the result were as follows : 1. In Durelon liquid 20 sec scrubbing & Vitrebond filling subgroup, shear bond strength was highest with measurements of 72.41(kg/
